Tadorna cristata Kuroda, 1917:1
Crested shelduck, Crested sheldrake, Korean crested shelduck, Phoenix-head(ed) sheldrake
Taxonomy & Nomenclature
Synonym/s: Pseudotadorna cristata Kuroda, 1917:1; Tadorna casarca x Querquedula falcata? Sclater, 1890
Conservation Status
Extinct
Last record: September 1916 (Hume & Walters, 2012); December 1916?; (May (June?) 1964?); 1964 (Martin et al., 2023)
IUCN RedList status: Critically Endangered
Unconfirmed reports of this species post-1964 suggest that it may persist in some small portion of its former range. Surveys are needed to search its vast historical range in order to assess its current status. Several reports from China in the 1980's indicate that that country should be the highest priority for surveys.
